IMPROVEMENT IN STOVE-PIPE DAMPERS.

Specification forming part of Letters Patent No. 131,963, dated October 8, 1872.

To all whom it may concern:

Be it known that I, MOSES F. MOODY, of Andover, in the county of Merrimack and State of New Hampshire, have invented an Improved Device for Regulating Dampers in Stove-Pipes, &e., of which the following is a specification Nature and Objects of the Invention.

Description of the Drawing. Figure l is a vertical side elevation of my device, showing the manner of its application to a damper-spindle Fig. 2 shows the device detached from the spindle and Fig. 3 shows the weightused.

General Description.

A shows an ordinary stove-pipe, and B a damper placed therein and revolving with the spindle (J, as usual. In the thumb-piece of the spindle, the piece shown in the drawing, a hole is drilled sufficiently large to allow the part c of the wire segment D (see Fig. 2) to pass through it. This piece having been passed through the hole in the spindle, it is wound around it suffieiently to keep the corrugated wire firmly inits place, and the weight E is then hung by a wire hook in any of the corrugations or depressions, and the damper will take a position according to which depression in the segment the weight is hung. The segment is made at a right angle, so that by suspending the weight at the corner b the damper will be perpendicular, and by changing its position to a the damper is brought to a horizontal bearing, and is therefore open, and by suspending the weight midway between these points the damper takes a position of forty-five degrees, and thus it may be regulated at pleasure to any angle by simply changing the place of the weight on the wire segment. It will be readily seen that the weight may be dispensed with and a pin, spring, &c., employed to retain the segment inany desired position, and therefore I do not confine myself to its use.

Claim.

The attachment for stove-dampers, consistin g of the corrugated segment D and weight or equivalent for holding the damper in any desired position in the pipe, substantiallyas described and specified.
